A proposed mitigation strategy uses submerged vanes and a submerged triangular prism structure to reduce local scour near bridge piers. Using the Flow3D Hydro CFD model, this work numerically evaluated the pier scour profiles. Together with a submerged triangular prism, submerged vanes can be tested to see if they can generate lift and change the flow field around bridge piers. It is anticipated that the flow field created by the convective momentum flux produced by submerged vanes and a submerged triangular prism will significantly lessen the local scour near bridge piers. To determine the proposed structure's potential for scour reduction, two numerical runs, including a baseline test, were conducted. It is anticipated that the proposed structure would lead to a decrease in the maximum scour depth and scour volume when compared to the scenario in which none of the mitigation structures are constructed. An earlier experimental study on flow dynamics by (Odgaard and Spoljaric in Sediment control by submerged vanes, 1986 [16]) was utilized to verify the submerged vane's effect on flows and assess the model's accuracy. The study found that using submerged vanes upstream of a submerged triangular prism enhances erosion mitigation potential compared to using the structure alone. Another very significant finding of our analysis is that the proposed construction has a larger flow separation zone, resulting in a smaller gradient of unfavorable pressure and slowing flow reversal upstream of the bridge pier. The proposed hydraulic structure is a successful method for scour counteraction at both new and old bridges, according to the research reported here.
